Sharpless 2-261 Lower's Nebula

One of the hidden treasures located in the outer edge of the Orion Arm of our Milky Way some 3300 light years away. This little gem is often passed over for more popular imaging targets in the area. It is named for the father-son team of astronomers who discovered it in 1939 and simply cataloged as an HII region. Not much is documented about it other than it is a faint emission nebula energized by yet another runaway star. There appears to be a fairly large shock wave or multiple bubbles in the center. Any comments on what this is would be appreciated. I can't find much information at all about this structure.

Imaged during my recent dark sky trip to Southern Utah. I processed this one in a much different way to enhance the deeper red tones and yellows in this nebula. This does tend to subdue the blue in the center but I was happy the bubble still shows clearly. My original SHO processing is included as a revision. I welcome any opinions or advice on which one is preferred or improvements to processing.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
